When installing offset grade stakes, the placement interval is based on which factor?

Explanation:
The spacing of offset grade stakes is tied to how the pipe is laid out, specifically the length of each pipe section. Stakes are used as reference points to verify grade and elevation at or near each joint as the trench is dug and pipe is installed. If pipe sections are short, you need stakes more often to check the grade; if sections are long, stakes can be spaced farther apart. This keeps a reference point close enough to each joint so the crew can confirm the line, slope, and alignment before proceeding. So the interval is based on the length of pipe sections because that distance determines where joints and critical checks occur. Soil type or pipe diameter don’t set the spacing, and total installation length isn’t the primary driver for stake spacing.
